Shanghai metal stamping parts manufacturer, stamping problems + 16 strict quality inspections

The technicians of the Shanghai metal stamping parts manufacturer have mentioned several problems with stamping: in daily production, they will encounter situations where the punching size is too large or too small (it may exceed the specifications) and the size of the punch is quite different. In addition to considering factors such as the design dimensions of the forming convex and concave dies, the processing accuracy and the blanking gap, Xiaoshuo thinks that the following aspects should be considered to solve the problem: ⑴. When the punching edge is worn, the tensile stress of the material increases Large, the tendency of stamping parts to turn over and twist increases. When turning over, the size of the punching hole will become smaller. ⑵. The strong pressure on the material causes plastic deformation of the material, which will cause the punching size to become larger. When the strong pressure is reduced, the punching size will become smaller. ⑶. The shape of the edge of the punch edge. If the end is trimmed with a slope or arc, the punching force will be slowed down, and the punching part will not be easily turned or twisted. Therefore, the punching size will become larger. When the end of the punch is flat (no bevel or arc), the punching size will be relatively small. Hardware, 15 years of ingenuity focused on metal stamping parts processing, 20000+ sets of stamping die customization production experience, monthly 100+ sets of mold processing capacity, daily production capacity of 3 million punching times, stamping accuracy up to 0.01mm, 16 quality inspection layers are strict check. It can quickly solve time-critical problems for you, solve stamping accuracy problems, and solve production quality problems. Choose, choose rest assured!
